در این تحقیق ابتدا به بررسی قیر و ویژگیهای آن مثل ساختمان شیمیایی، خواص فیزیکی و مکانیکی و چگونگی بهبود خواص آن با استفاده از افزودنیها به روشهای مختلف پرداخته شده است.سپس بمنظور شناخت بیشتر از پلیمرها مطالبی پیرامون ساختمان ملکولها، پلیمرها و ئیدروکربنهای حلقوی که تاکنون جهت تصلاح قیر استفاده شده ا ند و نحوه پلیمریزاسیون مونومرهای مختلف عنوان گردیده است. در ادامه با بررسی مواد معدنی و پلیمری گ...
The use of modifiers for bituminous binders has become common practice to enhance the performances asphalt materials. As a result, binder becomes more complex, with various phase morphologies. Conventional testing methods may not always be suitable. example, European standardisation committee is looking at different ways characterise Polymer modified Bitumen. RILEM Technical Committee 272-PIM ‘...
Increasing environmental awareness has led to a great research effort towards the formulation of increasingly sustainable pavements, mainly by developing bituminous mixtures incorporating waste materials. Furthermore, some materials have been proved be useful for enhancing performance road bitumen and products, so their use is potential solution ensuring environmental, economic, also technical ...
(2002) Numerical and experimental studies on the fracture behavior of rubber-toughened epoxy in bulk specimen and laminated composites. ABSTRACT To study the toughening mechanisms of liquid rubber (LR) and core-shell rubber (CSR) in bulk epoxy and composite laminate, experimental and numerical investigations were carried out on compact tension (CT) and double-cantilever-beam (DCB) specimens und...
The study of preparing silica/rubber composites used in tires with low rolling resistance in an energy-saving method is fast-growing. In this study, a novel strategy is proposed, in which silica was modified by combing alcohol polyoxyethylene ether (AEO) and 3-mercaptopropyltriethoxysilane (K-MEPTS) for preparing silica/natural rubber (NR) master batches. A thermal gravimetric analyzer and Rama...
